• Engine & Fitment Notes: This is the TURBO muffler. Naturally-aspirated (non-turbo) 416C, 416D, and 428C builds use a different muffler (112-5089). Confirm your engine is turbocharged before ordering
• Application: Reduces engine noise and routes exhaust gases away from the machine on the turbocharged 416–442 D-series backhoe loaders

Common Use Case or Symptoms:
Use when the muffler is rusted through, leaking exhaust, excessively loud, or physically damaged — a failed muffler allows exhaust gases and noise to escape at the machine rather than being routed away safely.
